HEMET (CBSLA.com) — Authorities are accusing a Hemet man of murdering his 5-year-old daughter, his wife (the girl’s step-mother) as well as slashing the throat of a third adult female — an acquaintance — Saturday evening.

Police told CBS2’s Greg Mills the suspect in custody.

There were two crimes scenes but police say one connection — Johnny Lopez, 33.

The bodies of the two females were found Saturday evening shortly after 9 p.m. inside a home in the 26000 block of Girard Street near Hemet.

Officials say Lopez killed his wife and his 5-year-old daughter at the Girard Street location. The adult woman was the girl’s step-mother.

In the second case, Lopez is accused of attacking another adult female and slashing her throat about a mile away on Sunset Lane.

Police would only say the third victim was an acquaintance of the suspect’s.

Capt. Scot Collins with the Riverside County Sheriff’s Department told Mills that woman is in critical condition at an undisclosed hospital.

Mill said the woman is “clinging to life.”

Police have not revealed how the deceased were killed or if a knife was used.

KCAL9’s Cristy Fajardo spoke to neighbors who said they heard arguing in the house.
